PULSE DISTRIBUTION AMPLIFIER WITH ETHERNET, 1 PPS to 100 MHz
The PD-15RMe is a TTL Pulse Distribution Amplifier that provides distribution for one pulse per second signals. The pulse distribution amplifier may also be used to distribute pulses with a repetition rate up to 100 MHz. The instrument distributes the user provided input signal to fifteen buffered isolated outputs. The outputs are designed to drive low impedance loads and long 50 or 75 ohm cables. The small propagation delay characteristics and low temperature coefficient of delay are essential for the distribution of high-quality timing signals. The instrument monitors the input and output signals levels. Faults are visible on the front panel LEDs and reported through the ethernet interface. The ethernet interface allows remote monitoring and control of the instrument. The PD-15RMe is available in a 1U, 19-inch rackmount enclosure, and the instrument runs on AC or DC power.
